ANTISLIPPING ATTACHMENT FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 577 ,4=7 5, dated February 23, 1897.

Application filed July 19, 1895. Serial No. 556,543. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH ZANDALAZINI, a

citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Oalk for Boots or Shoes, of which the following is a specification.

This invention relates to appliances to be fitted to a boot or shoe to prevent slipping, and aims to provide adevice for lumbermen and general use in slippery places and on icy surfaces.

The improvement consists in the provision of a device which will give to the movements of the foot, secure ease and comfort, be economical in construction, durable, and prevent abrasion and cutting of the attaching-straps.

Other objects and advantages are contemplated and will appear as the nature of the invention is unfolded, and to this end reference is to be had to the following description and the accompanying drawings, in which corresponding and like parts are referred to and indicated by the same reference-characters.

Figure 1 is a side elevation of a lumbermans boot, showing the attachment in position. Fig. 2 is a perspective view of the device. Fig. 3 is a detail section showing the manner of attaching the removable calks. Fig. 4. is a detail view'in elevation of a calk. Fig. 5 is a perspective view of an attachment for general use.

The device may be struck up, cast, or constructed in any economical way, and comprises a sole-plate 1, a heel-plate 2, a connecting-shank 3, and attaching-straps, which will be referred to at length hereinafter. In order to secure lightness, the parts 1, 2, and 3 will be open or skeleton form, and in order to provide for the giving of the device to the movements of the foot the sole-plate is hinged to the front portion of the shank 3, the hingejoint at being disposed so as to come about midway of the spring or hollow of the shoe or foot. The shank 3 is an integral part of the heel-plate, and an offset 5, connecting the rear end of the shank with the front end of the heel-plate, comes in front of the heel when the device is in position and assists materially in determining the position of the attachment and securing it in place.

The shank 3 is composed of longitudinal members, which are spaced apart and extend about parallel with each other and have their front ends curled and adapted to come upon opposite sides of a curl formed at the rear end of the sole-plate, the several curled portions alining and receiving a pin by means of which they are connected, so as toform the hingejoint 4. This construction results in the formation of a substantial joint between the heel I and sole plates and affords a support to the shank or hollow portion of the shoe.

Arms 6 project vertically from the sides of the heel-plate at or near the front end thereof and have openings or slots 7 at their free ends for the reception of an ankle-strap 8. An arm 9 at the rear end of the heel-plate extends in a vertical direction and curves to conform to the outline of the rear side of a boot or shoe, and has a loop or opening at its upper end to receive the counter-strap 10, the latter having 'its terminal portions secured to the anklestrap at a point forward of the ankle-joint.

The arms 6 and 9 are integral with the heelplate and extend up along the sides and back of the heel and prevent lateral displacement of the attachment when in position, and by having the attaching-straps connected therewith they are at such an elevation as to be .out of harms way, so as not to be abraded.

The sole-plate is formed at its edges with ears 11 to engage with the edges of the shoesole to hold the device against lateral displacement and has wings 12 for a like purpose to the cars 11 and also to receive the ends of a strap 13, which extends over the front portion of the foot to secure the attachment in place, the wings 12 having openings to receive the terminal portions of the footpunching or in any convenient way, and a new one substituted therefor and secured in place substantially in the manner herein described.

The device shown in Fig. 5 is substantially the same in construction as the attachment illustrated in the other views, with the exception that the front portion of the soleplate is removed and thecalks 16 are an integral part of the heel and sole plates, being triangular in shape, whereby points are provided to enter an icy or slippery surface. The calks at the edges of the plates are formed by triangular-shaped extensions, which are bent so as to extend about at right angles from the bottom side of the plates, and the calks located within the edges of a plate are provided byV-slits, the parts comprised between the slits being bent substantially as shown to form the calks.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new is An antislipping attachment for boots or shoes, comprising a sole-plate provided with calks and having its rear portion curved and terminating in a curl, and having correspondin g ears and wings at its edges, the wings havin g openings, a strap loopedthrough the openings of the wings and adapted to be buckled over the feet, a heel-plate provided with calks and having a rear and side Vertical extensions terminating in loops, and formed with a shank comprising longitudinal members which are deflected to form offsets to engage with the front of the heel and which curve in their length and terminate in curls to come upon opposite sides of the curl at the rear end of the sole-plate, a pin connecting the several curls, a counter-strap having connection with the loop of the said rear vertical extension, and an ankle-strap having connection with the said side vertical extensions of the heel-plate and with the ends of the counter-strap, substantially as shown for the purpose described.
